Agree, but unfortunately, it was not "a trace of covid"; it was a positive PCR for SC-2. People with positive PCRs for SC-2 do not have "covid"... not even a trace. They just have a fragment of SC-2 RNA up their noses.
What is SC-2? My understanding is that with a PCR test and high cycle thresholds, you could have any remnant of a past flu or cold present and it would be interpreted as "positive" for covid.
SC-2 is SARS-CoV-2, the virus that supposedly causes COVID-19. In theory, the PCR test should only detect RNA fragments from this virus, but as you say, some people claim that it could be "positive" if people have RNA of othe viruses up their noses. The most important concept in my mind (which has been a principle of medicine always) is that a positive test for RNA up your nose is not indicative of having a disease. Irrespective of whether the PCR detects only SARS-CoV-2 or other viruses, having a positive test does not mean that the person "has COVID"... or that they are infectious with anything. It just means that the person has a fragment of RNA of whatever virus (big deal). Best.

Thank you for clarifying. And agree.
Take care.
